Using git merge-base on the next-20080701 tag and current Linus tree I get
76 possible merge bases.  None of them appear to be the "right" one (if
I check out this tag and look at Next/merge.log the right answer appears
to be 1702b52 if I'm reading the log correctly).

Perhaps my best hope is to
        $ git checkout $tag Next/merge.log
        ... parse merge.log to figure out $base ...
